COOLING BEER.

SPECIFICATION forming pei-t of Lettere Patent No. 256,550, dated April18, 1882.

' Application tiled February 28, 1882. (No model.)

To all whom it may concern.- A

Be it known that I, DAVID YV. DAVIS, a citizen of the United States,residing at Dctroit, in the county of Wayne and State of Michigan, haveinventedcertain new and useful Improvements in the Process of CoolingBeer; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine, reference beinghad to the accompanying drawing, and to the letters and figuresot'reference marked thereon, which form apart of this specification.

My invention consists in a new process ot cooling beer, which processcan be applied to most of the devices in use for that purpose, undespecially to that class of coolers known as the Baudelot Cooler, andthe process is produced by the device that will be fully hercinafterdescribed.

The drawing shows the side elevation of my device, in which-- Arepresents the ordinary hot-beer-receiving tray from the delivery-pipeA', and has the angular bottom pierced with a series of holes, a.

B represents a broken side view of a tank or reservoir filled withsalted ice-water.

Upon the top of the tank B is a common force-pump, C, having asuction-pipe, C, eX- tending down into the salted ice-water in the tankB.

DDrepresent the usual coil of cooling-pipes, attached to the force-pumpC.

Dl is an elbow at the outer end of the upper coil of pipe D, to which issecured a perpendicular drain-pipe, D, the lower end of which drain-pipeextends into the tank B.

The hot beer is delivered into the drip-tray A from the boilers throughthe pipe A', and is generally about the temperature of 1900 Fahrenheit,when it drips through the perforations a upon the upper coil D, thenceupon plate d, to be formed into drops from the serl rated points d,rtofall upon the next pipe below, and soon to the lowest pipe of the coil,when it is brought to the proper degree of cold to be drained into casksto be stored or for further treatment.

The process used in my invention will require less length of cooling-pipes to accomplish the same degree of temperature in the beer, as itis a well-understood fact that salted ice-water is many degrees colderthan simple ice-water. Hence if saltedice-water is used as a coolingagent it will, when. applied by the same means, produce the same resultin a much less time. The tank B, benglled with water containing ice andsaturated with salt, the force-pump C is pnt into operation, whichforces the salted ice-water upward through all the horizontal coils ot'pipes D to the upper one, thence the partially-warmed salted icewater isreturned through the downward drainpipe D into the tank B,` to be againmingled with the colder contents of the tank, which may be kept inagitation by any wellknown means so as to prevent congelation and tokeep the entire contents at about the same temperature. At the same timethebeer, hot at rst, is trickling from the receivingtray upon the coolpipes, thence onto the next lower pipe that is cooler than the upperone, and so on until the lower pipe is reached, in which the coldestsalted ice-Wateris, when the beer is cool enough to store away. Commonice-water is in temperature above 320 Fahrenheit, while salted ice-wateris just above zero, or near to that temperature. Hence, as a coolingagent the difference between it and siniple ice-water is about 320,which applied in and through the pipes upon which hot and warm beer isdripping, it is apparent that the beer is cooled in a less time or by ashorter device through which the cooling agent is forced.

I am aware that ice-water has been passed through pipes to cool the beerfrom the boilers. I am also aware that the devices used in making iceartificially are used in cooling beer, neither of which do I claim. Nordo I claim the construction seen in Patent No. 230,694, or theconstruction in any other patent; but

The process of cooling beer by forcing salted ice-water int-o andthrough a coil of coolingpipes upon which thehot beer drips, and thenreturning the salted ice-Water back into the tank from which it wastaken, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.

DAVID WV. DAVIS.
